The above doesn't say anything about calibration but I'm gonna guess Graham B. and the guys at LPE did some stuff to the cal, too.

The car had stock exhaust manifolds and stock exhaust with a mild/wild switch.

It was running on 109-oct unleaded racing gas.

Reportedly this car makes almost 740 at the wheels and was in the 9s with three passes on 12/7/09. On the best one, the car went 9.81 at 145.74....Holy crap!

The venue was Maryland International Raceway near Budds Creek MD.

There is a video of this car at www.lingenfelter.com/video doing the 9.81. Take note of the guy's starting line technique. Not popping the clutch but engaging it quickly. The car is an '09 which doesn't have launch control so the driver is pretty freakin' good.
